Description
Stand der TechnikState of the art
Elektrische Energiespeicher, beispielsweise Batterien, wie sie in Elektrofahrzeugen zur Anwendung kommen, umfassen üblicherweise eine Speicherzelle und eine Steuereinheit, die auch als Batteriemanagementsystem (BMS) bezeichnet wird. Für den Betrieb der Batterie ist üblicherweise Kenntnis oder zumindest eine Annahme über diverse Betriebsparameter der Batterie nötig. Beispielsweise bildet der innere Widerstand der Batterie eine Eingangsgröße für diverse Betriebssituationen wie beispielsweise eine Schnellladestrategie oder die Ermittlung eines Ladezustands der Batterie.Electrical energy stores, for example batteries, such as those used in electric vehicles, usually comprise a storage cell and a control unit, which is also referred to as a battery management system (BMS). Knowledge or at least an assumption about various operating parameters of the battery is usually necessary for the operation of the battery. For example, the internal resistance of the battery forms an input variable for various operating situations, such as a quick charging strategy or the determination of a state of charge of the battery.
Verfahren zum Betreiben eines elektrischen Energiespeichers, bei dem Betriebsparameter wie z. B. der elektrische Innenwiderstand der Batterie durch das BMS abgeschätzt werden, sind vom Markt her bekannt. Hierfür geht das BMS üblicherweise davon aus, dass sich die Batterie wie eine Vergleichsbatterie, zu der umfangreiche Laboruntersuchungen vorliegen, verhält und schätzt entsprechend die Betriebsparameter ab. Üblicherweise wird hierfür das BMS bei Produktion bedatet, wobei eine aktualisierung der Daten oder eine indivisualisierung auf die spezifische Batterie nicht vorgesehen ist. Umfasst die Abschätzung der Betriebsparameter durch das BMS aufwendige Algorithmen, ist hierfür entsprechende Rechenleistung innerhalb des BMS nötig.Method for operating an electrical energy store, in which operating parameters such. B. the electrical internal resistance of the battery can be estimated by the BMS are known from the market. For this purpose, the BMS usually assumes that the battery behaves like a reference battery, for which extensive laboratory tests are available, and estimates the operating parameters accordingly. Usually the BMS is used for this during production, whereby an update of the data or an individualization for the specific battery is not provided. If the BMS estimates the operating parameters by complex algorithms, this requires corresponding computing power within the BMS.
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Verfahren zum Betreiben eines elektrischen Energiespeichers, der eine Speicherzelle zum Speichern von elektrischer Energie und eine Steuereinheit umfasst, wobei die Steuereinheit eingerichtet ist, Zustandsgrößen des elektrischen Energiespeichers zu erfassen, hat demgegenüber den Vorteil, dass von der Steuereinheit erfasste Zustandsgrößen an eine Recheneinheit außerhalb des elektrischen Energiespeichers übertragen werden, und dass ein Betrieb des elektrischen Energiespeichers auf Basis von Betriebsparametern erfolgt, die von der Recheneinheit bereitgestellt werden. Das Bereitstellen von Betriebsparametern durch die Recheneinheit hat insbesondere den Vorteil, dass die Steuereinheit des elektrischen Energiespeichers weniger Rechenleistung zur Verfügung stellen muss, somit beispielsweise ein im Vergleich zum Stand der Technik günstigerer Mikrocontroller in der Steuereinheit verwendet werden kann.The method according to the invention for operating an electrical energy store, which comprises a memory cell for storing electrical energy and a control unit, the control unit being set up to record state variables of the electrical energy store, has the advantage over the fact that state variables recorded by the control unit to a computing unit outside of the electrical energy store are transmitted, and that the electrical energy store is operated on the basis of operating parameters that are provided by the computing unit. The provision of operating parameters by the computing unit has the particular advantage that the control unit of the electrical energy store has to provide less computing power, so that, for example, a microcontroller which is cheaper than the prior art can be used in the control unit.
Vorteilhaft ist, dass die von der Recheneinheit bereitgestellten Betriebsparameter unter Verwendung der von der Steuereinheit erfassten Zustandsgrößen bestimmt werden. Mit anderen Worten kann somit vorteilhafter Weise die Bestimmung der Betriebsparameter von der Steuereinheit an die Recheneinheit ausgelagert werden.It is advantageous that the operating parameters provided by the computing unit are determined using the state variables detected by the control unit. In other words, the determination of the operating parameters can thus advantageously be outsourced from the control unit to the computing unit.
Vorteilhaft ist, dass die Betriebsparameter unter Verwendung von Modellen ermittelt werden, wobei die Modelle geeignet sind, aus den erfassten Zustandsgrößen des elektrischen Energiespeichers Schätzzustandsgrößen des elektrischen Energiespeichers zu ermitteln und die Betriebsparameter ausgehend von den Schätzzustandgrößen ermittelt werden. Unter Zustandsgrößen sind dabei insbesondere solche physikalischen Größen zu verstehen, die mittels einer geeigneten Sensorik in oder an dem elektrischen Energiespeicher erfasst werden können, wie beispielsweise eine Temperatur, ein Strom, eine Spannung oder eine elektrische Ladung. Schätzzustandsgrößen sind solche physikalischen Größen, die ebenfalls den Zustand des elektrischen Energiespeichers beschreiben, allerdings nicht mittels einer Sensorik direkt am elektrischen Energiespeicher erfasst wurden, sondern ausgehend von den erfassten Zustandsgrößen abgeschätzt wurden. Betriebsparameter sind insbesondere physikalische Größen, die als Eingangsgröße für den Betrieb des elektrischen Energiespeichers verwendet werden, beispielsweise der Innenwiderstand des elektrischen Energiespeichers. In einer vorteilhaften Ausgestaltung sind die Betriebsparameter selbst Schätzzustandsgrößen. It is advantageous that the operating parameters are determined using models, the models being suitable for determining estimated state variables of the electrical energy store from the detected state variables of the electrical energy store and the operating parameters being determined on the basis of the estimated state variables. State variables are to be understood in particular to mean those physical variables that can be detected by means of a suitable sensor system in or on the electrical energy store, such as a temperature, a current, a voltage or an electrical charge. Estimated state variables are physical quantities that also describe the state of the electrical energy store, but were not recorded directly on the electrical energy store by means of a sensor system, but were estimated on the basis of the recorded state variables. Operating parameters are, in particular, physical variables that are used as an input variable for the operation of the electrical energy store, for example the internal resistance of the electrical energy store. In an advantageous embodiment, the operating parameters are themselves estimated state variables.
Vorteilhaft ist, dass die von der Recheneinheit bereitgestellten Betriebsparameter mittels neuronaler Netze ermittelt werden. Somit ist es insbesondere möglich, die Betriebsparameter bzw. Schätzzustandsgrößen mit einer hohen Genauigkeit zu ermitteln und dabei die üblicherweise durch die Recheneinheit, bei der es sich beispielsweise um eine Cloud handeln kann, bereitgestellte Rechenleistung vorteilhaft auszunutzen.It is advantageous that the operating parameters provided by the computing unit are determined by means of neural networks. It is thus possible, in particular, to determine the operating parameters or estimated state variables with a high degree of accuracy and to use the computing power usually provided by the computing unit, which can be a cloud, for example, to advantage.
Vorteilhaft ist, dass sich der elektrische Energiespeicher in einem Fahrzeug befindet und eine Verbindung zwischen der Steuereinheit und der Cloud über ein Drahtloskommunikationsmodul erfolgt. Bei dem Drahtloskommunikationsmodul kann es sich dabei insbesondere um ein Modem, beispielsweise ein GSM-Modem, handeln.It is advantageous that the electrical energy store is located in a vehicle and that a connection is established between the control unit and the cloud via a wireless communication module. The wireless communication module can in particular be a modem, for example a GSM modem.
Vorteilhaft ist, dass die Steuereinheit Werte der durch die Cloud bereitgestellten Betriebsparameter speichert und solange zum Betrieb des elektrischen Energiespeichers verwendet, bis aktualisierte Werte der Betriebsparameter von der Cloud verfügbar sind. Üblicherweise ändern sich die Betriebsparameter zum Betreiben des elektrischen Energiespeichers auf langsamen Zeitskalen, insbesondere dann, wenn es sich bei den Betriebsparametern um Schätzzustandsgrößen oder unmittelbar aus den Schätzzustandsgrößen abgeleitete Größen handelt. Somit ist es nicht erforderlich, auf kurzen Zeitskalen, die zum Betrieb des elektrischen Energiespeichers verwendeten Betriebsparameter zu aktualisieren. Durch das Speichern der aktuell verwendeten Betriebsparameter kann somit vorteilhafter Weise ein Datenverkehr zwischen dem Drahtloskommunikationsmodul und der Cloud reduziert werden. Besonders vorteilhaft ist, dass auf diese Weise auch eine erhöhte Robustheit gegenüber einer Unterbrechung der Verbindung zwischen Drahtloskommunikationsmodul und der Cloud sichergestellt werden kann.It is advantageous that the control unit stores values of the operating parameters provided by the cloud and uses them to operate the electrical energy store until updated values of the operating parameters are available from the cloud. Usually, the operating parameters for operating the electrical energy store change on slow time scales, in particular when the operating parameters are estimated state variables or variables derived directly from the estimated state variables. It is therefore not necessary to use short time scales to operate the electrical energy store update used operating parameters. By storing the currently used operating parameters, data traffic between the wireless communication module and the cloud can advantageously be reduced. It is particularly advantageous that an increased robustness against an interruption of the connection between the wireless communication module and the cloud can also be ensured in this way.
Vorteilhaft ist eine Vorrichtung, die eingerichtet ist, jeden Schritt des erfindungsgemäßen Verfahrens durchzuführen. Vorteilhaft ist außerdem ein Computerprogramm, das eingerichtet ist, jeden Schritt des erfindungsgemäßen Verfahrens durchzuführen, wenn das Computerprogramm auf einer Recheneinheit abläuft.A device which is set up to carry out each step of the method according to the invention is advantageous. A computer program that is set up to carry out each step of the method according to the invention is also advantageous if the computer program runs on a computing unit.
Vorteilhaft sind außerdem ein elektrischer Energiespeicher, der die erfindungsgemäße Vorrichtung umfasst sowie ein Fahrzeug, das die erfindungsgemäße Vorrichtung umfasst.Also advantageous are an electrical energy store that includes the device according to the invention and a vehicle that includes the device according to the invention.
